  13      A fake input stream for pdb's interactive debugger.  Whenever a
  14      line is read, print it (to simulate the user typing it), and then
  15      return it.  The set of lines to return is specified in the
  16      constructor; they should not have trailing newlines.

  32  Test calling some IPython magics from ipdb.
  33  
  34      First, set up some test functions and classes which we can inspect.
  35  
  36      In [1]: class ExampleClass(object):
  37         ...:    """Docstring for ExampleClass."""
  38         ...:    def __init__(self):
  39         ...:        """Docstring for ExampleClass.__init__"""
  40         ...:        pass
  41         ...:    def __str__(self):
  42         ...:        return "ExampleClass()"
  43  
  44      In [2]: def example_function(x, y, z="hello"):
  45         ...:     """Docstring for example_function."""
  46         ...:     pass
  47  
  48      In [3]: old_trace = sys.gettrace()
  49  
  50      Create a function which triggers ipdb.
  51  
  52      In [4]: def trigger_ipdb():
  53         ...:    a = ExampleClass()
  54         ...:    debugger.Pdb().set_trace()
  55  
  56      Run ipdb with faked input & check output. Because of a difference between
  57      Python 3.13 & older versions, the first bit of the output is inconsistent.
  58      We need to use ... to accommodate that, so the examples have to use IPython
  59      prompts so that ... is distinct from the Python PS2 prompt.
